In this study, we empirically investigated the internal consistency among priorities in manufacturing strategy, manufacturing activity program performances and managerial performance indices in domestic electronic manufacturing firms. The test results show that there exist several significant internal consistencies with managerial implication related in research model. Especially, priority in quality shows most significant consistency through manufacturing activity program performances and managerial performance indices.

Manufacturing is fast entering a new age of industrial excellence that is being called "Agile Manufacturing." The goal of Agile Manufacturing is to link customers, suppliers, and the manufacturing system into a super-efficient confederation to produce a variety of products quickly and at a low cost. In order to improve the quality of the study of production input control(PIC) in a job shop manufacturing system by reducing the significant gap between research models and models of actual manufacturing systems, the previous line of research on PICs in a job shop manufacturing system is extended by integrating customers and suppliers with the manufacturing system. Then, a set of measures is developed to evaluate PICs, measures that reflect concerns of customers and suppliers as well as concerns of the manufacturer. Also, a weighted overall measure (with various cases to represent different possible weights of manufacturer's emphasis on the performance measures) is used to synthesize all the performance measures. Then, for each case, various existing PICs are evaluated in combination with various priority dispatching rules(PDRs).

Semiconductor manufacturing is one of the most complex and capital-intensive processes composed of several hundreds of operations. In today’s competitive business environments, it is more important than ever before to manage manufacturing process effectively to achieve better performances in terms of customer satisfaction and productivity than those of competitors. So, many semiconductor manufacturing companies implement advanced planning and scheduling (APS) system as a management tool for the complex semiconductor manufacturing process. In this study, we explain roles of production planning and scheduling in semiconductor manufacturing and principal factors that make the production planning and scheduling more difficult. We describe the APS system implementation project at Korean semiconductor manufacturing company in terms of key issues with realistic samples.

In recent years, developed and developing country such as U.S., Japan, and China push forward to enhance their manufacturing industry through national policies such as advanced manufacturing(U.S.), Industrie 4.0 (Germany), and Made in China 2025. Also, in Korea, Ministry of Trade, Industry, and Energy(MOTIE) claimed Manufacturing3.0 for encouraging domestic manufacturing industry. Manufacturing industry plays an important role in encouraging economy and employment. In this paper, we survey, analyze and summarize the current national policy for enhancing manufacturing industry.

Additive Manufacturing defines the fabrication of objects by successive consolidation of materials, layer by layer, according to a three-dimensional design. The numerous technologies available today were recently standardized into seven categories based on the general method. Each technology has its own set of advantages and limitations. Though it very much depends on the field of application, major assets of additive manufacturing compared to conventional processing routes are the ability to readily offer complexity (in terms of intricate shape and customization) and significant reduction of waste. On the other hand, additive manufacturing often suffers of relatively low production rates. Anyhow, additive manufacturing technologies is being given outstanding attention. In particular, metal additive manufacturing emerges as of great significance in industries like aerospace, automotive and tooling. The trend progresses toward full production of high value finished products.

The use electron-beam(E-beam) manufacturing system provides a means to alleviate optic exposure equipment's problems. We are developing an E-beam manufacturing system with scanning electron microscope(SEM) function. The E-beam manufacturing system consist of high voltage generator, beam blanker, condenser lenses, object lenses, stigmator and stage. The development of E-beam manufacturing system is used on the method of remaking SEM's structure. The functions of SEM are developed. It is important for the test of E-beam performance. In E-beam manufacturing system and SEM, beam focus is important function. In this paper, we propose intelligent remote control function for beam focus in E-beam manufacturing system. The function extends the user's function and gives convenience.

Modern manufacturing systems should cope with the frequent changes in a product model and disturbances in manufacturing process. The control system of such systems must cover a constant adaptation and high flexibility. Holonic Flexible Manufacturing Cell(HFMC) is introduced to handle these issues more successfully. It is based on the concept of autonomous co-operating agent, called 'Holon', which is a building block of a manufacturing system for transforming, transporting, storing and/or validating information and physical objects. In this paper the basic structure of the HFMC is represented by using Unified Modeling Language and Open architecture cell controller is developed for effective integration components of a manufacturing system. Also a new control model, called MuLOM(Multi-Layered Operation Model), is suggested to represent the control behaviour for a holonic flexible manufacturing cell control system.

This study closely examines quality management's realities which manufacturing firms have and effective result controls access formula by comparison and analysis on the product of introduction quality control realities and quality management of manufacturing firms in Chollabukdo. In order to accomplish the purpose of this study, this research was progressed as order of literature review and survey. After literature review this study drew up questionnaire on the basis of foregoing literature and executed survey on manufacturing business taking TQM(Total Quality Management) in Chollado's area. The result of analysis are as follows. First, according to the analysis manufacturing of industry's realities, investment in TQM techniques seems to contribute to the performance of manufacturing firms, but most of manufacturing firms quality control do not have strategic orientations. Conseqently, general and strategic quality management system suitable for the realities of manufacturing industry are required. Second, It seems that manufacturing industry didn't recognize strategic importance for competitive advantage. Namely, It was found that firms with less TQM executed non-strategic quality management, compared with firms more TQM.
